I think Heald Pond was the destination for my first ever "orienteering" experience, though I don't really count it as such. We were started in groups at different spots along the road behind the high school, and had to get to the pond pretty much on a compass bearing, where we had a picnic. (I think some of the roads in that area weren't built yet, or maybe they were there but with no houses on them.) This was in 10th grade French class, where we had a teacher on an exchange program from France who would do anything to get out of the classroom. We were supposed to do this while speaking French the entire time.
